Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514296, here are decompositions:

5 + 31514291 = 31514296
29 + 31514267 = 31514296
137 + 31514159 = 31514296
353 + 31513943 = 31514296
419 + 31513877 = 31514296
479 + 31513817 = 31514296
503 + 31513793 = 31514296
509 + 31513787 = 31514296

Showing the first eight; more decompositions exist.
